SPECIFICATION forming part of Letters Patent N 0. 618,402, dated January31 1899.

Application filed December 27,1897. Serial No. 663,541. (No model.)

To all whom it may concern:

Be it known that I, JAMES EDGE, mill manager, of High street, Gort on,in the county of Lancaster, England, have invented certain Improvementsin Flat-Stripping Motions for Carding-Engines, (for which I haveobtained Letters Patent of the United Kingdom of Great Britain andIreland, numbered 18,115, dated August 15, 1896,) of which the followingis a specification.

My invention relates to improvements in flat-stripping motions forcarding-engines; and the object of my invention is to provide mechanismcapable of stripping the short fibers from the flats more eflicientlythan the mechanism hitherto provided.

My invention consists, essentially, in means for giving to thestripping-comb an oscillating motion about an axis in conjunction with arapid downward movement.

In the accompanying drawings, in all the views of which the same lettersof reference are employed to indicate corresponding parts, Figure 1 is apartial front elevation, and Fig. 2 is an end elevation,of apparatusconstructed according to my invention. Fig. 3 is an end elevation, andFig. S" a partial front elevation, of a part of a slightly-diiferentarrange ment of apparatus constructed according to myinvention. FigsAand 5 are end elevations of parts of other slightly-differentarrangements of apparatus constructed according to my invention; andFig.6 is a front elevation, partly in vertical section, of arrangementsemployed according to my invention to move the stripping-comblengthwise. Fig. 7 represents a side view and a plan of a modificationof devices for turning the stripping-comb shaft. Fig. 8 represents aside view and a plan of another modification of such parts. Figs. 9, 10,and 11 represent a modification of the devices for producing alongitudinal movement of the stripping-comb shaft.

It is obvious that parts similar to some of those illustrated in theaccompanying drawings as applied to one side of the cardingengines, ofwhich portions are illustrated in the said drawings, are necessarilyemployed at the other side of such carding-engines.

The stripping-comb A, which is employed according to my invention, maybe of any suitable form and may be supported in any suitable manner,being in the accompanying drawings illustrated as secured to a rod, bar,or shaft a, but must be mounted and capable of being oscillated inbearings carried by arms 0, which are placed one at each side of thecarding-engine and are arranged to be oscillated about the axis of ashaft D, fast upon which they mounted. The shaft D passes over the topof the carding-engine in the ordinary way and receives an oscillatingmovement, being provided with an arm which projects from it and carriesat its lower end a bowl 6, resting upon a cam F, which is revolved inany suitable manner, such as by being fixed upon or connected with somesuitable revolving part of the carding-engine. The arrangement describedinsures that the oscillating movement imparted to the shaft D will beconveyed through the arms 0 to the stripping-comb A. According to myinvention I cause the downwardmovements of the stripping-comb, in whichthe short fibers are stripped from the flats, to be quicker than theupward movements of such strippingcomb, and I do this by forming thatpart f of.

the cam F which by its action on the bowl 6 brings about the upwardmovement of the comb with a very gradual progression in a directionoutward from the axis of said cam the comb A to move more rapidly whilestripping the flats than when ascending between one downward strokeandthe next, and by so doing I render the action of the comb moreeffective than it would otherwise be. It is obvious that the cam F maybe so formed that two or more downward and two or more upward strokesshall be perform ed by the comb A during each revolution of the cam F.In Figs. 1 and 2 the parts are shown in the positionswhich they occupywhen the comb A I is at the highest point of its stroke and quite clearof the flats, of which only one is indicated at G, 9 indicating one ofthe disks or bowls around which the flats are made to pass.

Besides imparting to the stripping-comb A an oscillating movement of thekind already described I impart to it during such movement an additionalmovementthat is to say, an oscillating movement about its axis or theaxis of the shaft, bar, or rod a, on which it is mounted-and thisadditional oscillating movement may be obtained in several ways, ofwhich I will proceed to describe some by way of instances. In one methodof imparting the said additional movement I fix on one side of thecarding-engine, in a suitable position, a bracket II, formed with a holeor slot h, and on the comb or the part supporting it I fix an arm,finger, lever, or the like J, carrying a stud or pin j, which entersinto the hole It. The stud j may be arranged to be adjustable, as isindicated in Fig. '7, which shows the studj as passing through a slot j,formed in the arm J, and as provided with a nut j by means of which itmay be'secured in said arm. In this arrangement while the cam F impartsto the comb A the oscillation hereinbefore described the movement of thecomb A in relation to the bracket H causes such comb A to also oscillateabout its axis. Instead of the stud j being fixed in the arm J it may befixed in the bracket II, and the hole or slot 9' to receive such stud j,may be made in the arm J, as illustrated by Fig. 8, and although it ispreferable to employ one arm J and one bracket II an arm J and bracketII may be provided at each side of the carding-engine. In another methodof imparting the said additional movement to the strippingcomb the stud7' is dispensed with altogether, the arm J being formed in the mannerindicated in Figs. 3 and 3 and made to project through a hole or slot hin the bracket H, the length .of the hole or slot determining the amountof the additional movement imparted to the comb, and in yet anotherarrangement for the said purpose an arm J projects on both sides of thestripping-comb, one part of the arm J bearing with one side against thebracket II, a spring or a weight It upon the other part of the arm J, asindicated in Fig. 4, serving to keep such arm J in contact with thebracket H. Further, instead of using an arm and a slotted bracket I mayform on the bracket a rack K, as shown in Fig. 5, and fix on the comb orthe shaft, rod, or bar on which it is mounted a pinion or sector L,which gears into or engages with the rack K, and so causes the comb tooscillate. From what I have said it is obvious that the additionaloscillation of the stripping-comb can be obtained in many ways withoutdeparture from the nature of my invention.

In addition to giving the movements above described to thestripping-comb my invention also consists in imparting to suchstrippingcomb a longitudinal movem ent,so as to enable it to still moreeffectually strip the flats, and to obtain this movement I form in thecombshaft a, as shown in Fig. 6, a spiral or helical groove,into which astationary peg, pin, or the like a passes, or I form, as shown in Figs.9

made to project, in either of which arrangements the oscillation of thecomb-shaft will cause such comb-shaft to move lengthwise .both in theupward stroke of the comb and the downward stroke thereof.

Set-screws, lock-nuts, and other requisite and suitable means forenabling the various parts of the mechanism to be adjusted relatively toeach other are provided.
